Prepare fava beans. Bring a pot of water to a boil with a hefty pinch of salt and prepare an ice bath. Shell the favas and place in the boiling water. Boil for 60 seconds and immediately transfer to an ice bath. Once cool, shell the favas by piercing with your thumb and removing the inner-most bean.

Shred the rye bread by grated, pulsing in a food processor, or pulling apart with your fingers. I like to have small crumb-like pieces and a few slightly larger pieces to vary texture. Melt 1 tablespoon butter in a pan over medium-low heat and add the bread. Toast until the bread is golden and the crumbs have crisped. Transfer to a boil.

Wipe out the pan and return to a low-heat. Add the remaining 2 tablespoon of butter along with the lemon zest, salt, and pepper. Add the shelled favas and cook for roughly a minute, just to warm the beans. Remove from heat and stir in the dill.

Place spinach in a large bowl. Add the favas along with most of the toasted bread. Toss together then top with sliced soft-boiled eggs, the remaining toasted bread, and a sprinkle of dill.
